Title: Scanning path diagnosing circuit
Inventor: NAGAYAMA YASUHIRO
IPC: G06F11/22
Filed: 1985-08-23
Abstract: PURPOSE:To detect rapidly any failure out of '0' regeneration and '1' regeneration by the small number of hardwares by connecting an exclusive OR circuit to a flip flop (FF) in a scanning path. CONSTITUTION:At checking the normality of a scanning path in a logical card 4, a signal '1' is supplied to a test mode terminal 23.

Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To inform, in the case a copy is made in a full-color image forming mode, a third person of the massage for the purpose of offering assistance for copying operation and monitoring prohibited copying by providing an informing means or the like for giving, in response to the operation to form a full- color copy image, the information to a third person except an operator which can be recognized. SOLUTION: In the case the copying operation to form a full-color image is being carried out, a full-color image copy start signal is transmitted to a computer PC 60 from IC 148 for an input/output control, and its message is displayed on a CRT 61, thereby informing the third person (supervisor) that a copy is being made in the full-color image formating mode. Then, the device judges whether the image of an original document is that of a banknote or not. In case the device recognizes it as the banknote, a banknote recognition signal is transmitted to the PC 60 from IC 148 for the input/output control, and a screen indicating the possibility of illegal copying appears onto the CRT 61. Thus, the third person can monitor and check whether a prohibited copy is taken or not.

Title: Optical head device and optical information apparatus
Inventor: KANEUMA YOSHIAKI
IPC: G11B7/13
Filed: 1994-08-05
Abstract: PURPOSE:To obtain a stable focus error signal by providing a photodetector for receiving diffracted light generated by directing a light beam to a hologram coupling lens by a photodetector. CONSTITUTION:A light beam reflected by an information recording/reproducing surface of an optical disk 4 is directed to an objective lens 1 coupled to a hologram. The + primary diffraction light 6 diffracted by the hologram falls on detector 7 disposed near a light source 2. Focus and tracking error signals are obtained from signal intensity of divided zones of the detector. Since the hologram is fixed by using coupling means to the lens, the diffracted light generated from the hologram is not moved on the detector 7 irrespective of the movement of the lens by tracking. Accordingly, a stable focus error signal can be obtained in parallel with the tracking follow-up.

Abstract: PURPOSE:To realize a complete single-crystallization of an Si thin film and to reduce procesing time of a wafer substantially by a method wherein a narrow beam which is longer than the whole excited domain is radiated onto a substrate and the beam is scanned to the direction of the width relatively against the substrate. CONSTITUTION:A layer shape electron beam 11 accelerated by approximately 1-10keV is condensed along the scanning direction and radiated onto the surface of a wafer 8 on which the beam 11 becomes the thinnest. As a result, an Si thin film 13 on the surface of the wafer 8 is melted and a thin line of a melted region 17 crossing the surface of the wafer 8 is produced. If the electron beam 11 is scanned to the direction of the arrow 12 relatively against the wafer 8, the whole area of the Si film 13 is single-crystallized by one scanning. In this case, the thickness, intensity and scanning speed of the electron beam 11 on the surface of the wafer 8 are determined by the relation between each of above item and heat radiation condition near the surface of the wafer 8.

Title: Dust cover for shock absorber
Inventor: EJIMA KAZUYOSHI
IPC: B60G15/06
Filed: 1994-08-05
Abstract: PURPOSE:To provide a dust cover of high durability hard to generate a crack, caused by earlier degradation than other parts, to the crest part of the bellows cylinder part of the dust cover even under long-term use by making each crest part of the bellows cylinder part thicker than the parts adjacent to the crest part. CONSTITUTION:When a plate member 4 rises in contact with the end part 8B of a dust cover by the bound of a wheel, a bellows cylinder part 8A is compressed so as to start contraction in the axial direction of a piston. That is, plural crest parts 8C protruding outward in the radial direction of the bellows cylinder part 8A approach the adjacent crest parts, and plural trough parts 8D recessed outward in the radial direction approach in the same way. As the trough parts 8D approach each other, tensile stress is generated to the crest parts 8C, but since the thickness of the bellows cylinder part 8A is gradually thickened toward the crest part 8C from the trough part 8D, and the area of the crest part 8C is enlarged so as to have the maximum thickness d3 at the apex of the crest part 8C compared to the thickness d2 of the adjacent part and the thickness d1 of the trough part. Tensile stress is thereby dispersed all around the crest part 8C.
